Product Overview

The 991 Thrust Transmitter is designed primarily for OEMs of centrifugal air compressors, small pumps, motors, or fans who require a simple 4 to 20 mA proportional axial displacement (thrust) signal for their machinery control system. This 2-wire, loop-powered device accepts input from a 3300 NSv proximity probe and matching extension cable (available in 5 m and 7 m system length options). The transmitter conditions the signal into engineering units proportional to the shaft's axial position and provides it as a 4 to 20 mA industry-standard signal for control system input.

Key Features
  • Integrated Proximitor Sensor requires no external unit
  • Non-isolated "PROX OUT" and "COM" terminals plus coaxial connector provide dynamic vibration and gap voltage signal output for diagnostics
  • Non-interacting zero and span potentiometers under the Transmitter label support loop adjustment
  • Test Input pin allows quick verification of loop signal output using a variable DC voltage source
  • Power-up Inhibit circuit eliminates signal errors due to line voltage transients
  • Not OK/Signal Defeat circuit prevents high outputs or false alarms from faulty proximity probes or loose connections
  • Choice of DIN-rail clips or bulkhead mounting screws as standard options
  • Potted construction for high humidity (up to 100% condensing) environments
  • Compatibility with 3300 NSv proximity probe allows installation in small spaces
